In the lab, you generated bisulfite ion (HSO3' ) from a solution of sodium metabisulfite (Na2S205) according to the following net ionic equation,
S20,2- -(aq) + H20 (1)= 2HSO3(aq)
Calculate the concentration in M) of HSO in a solution prepared by mixing 10.00 mL of 0.00210 M
Na2S205
with 2.00 mL of water.

Complete the sentence. the lower the hydrogen ion concentration, the the ph. higher lower closer to 7 closer to 0

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
